Title: Control circuit for higher harmonic compensating device
Inventor: MIYASHITA TAKESHI
IPC: G05F1/70
Filed: 1990-07-23
Abstract: PURPOSE:To use the inverter capacity for reactive power compensation even when a compensation higher harmonic is small by providing a compensation current command changing means for changing an output partial charge of a higher harmonic compensation portion and a reactive power compensation portion in a current command signal for inverter control by a load current detection value. CONSTITUTION:A compensation current command changing means is constituted of a current detector 6, a p-q converting circuit 7, a low-pass filter 8, a high-pass filter 9, a reactive power command limiter circuit 10, a higher harmonic command limiter circuit 11, an adding circuit 12, and a compensation current command changing circuit 13. These compensation current command changing means 6 - 13 change an output partial charge of a higher harmonic compensation portion and a reactive power compensation portion in a current command signal for inverter control by a load current detection value. Accordingly, when a higher harmonic is small, a partial charge of the reactive power compensation portion increases, and always becomes roughly constant as the output capacity of an active filter. In such a way, the inverter capacity can be used for reactive power compensation.

Title: Liquid fuel injection device
Inventor: SUZUKI YUTAKA
IPC: F23N1/02
Filed: 1982-11-04
Abstract: PURPOSE:To make it possible to maintain the complete combustion of a fuel by a method wherein the amount of injection of the fuel is controlled by varying the pressure of the fuel in a fuel passage through a changeover valve arranged in a fuel return passage and an injection nozzle air quantity control device is operated in correspondence with the variation of the pressure of the fuel. CONSTITUTION:The opening and closing time of the changeover valve 6 or the opening degree of the valve is changed properly by operating a dial 12 so that the flow rate of the fuel returning to a liquid fuel vessel 1 from the fuel passage 4 is changed. In this case, as a pump 2 is a discharge pump of constant pressure, the pressure of the fuel in the fuel passage is changed to thereby control the amount of injection of the fuel injected from the injection nozzle without graduations. At the same time, the fluid pressure acting on a diaphragm 22 changes in proportion to the variation of the pressure in the fuel passage so that a valve body 20 adopted to open and close an air passage 25 is controlled and the quantity of air supplied near the injection nozzle is controlled. Consequently, the ratio of the amount of fuel injection to the quantity of supply air is kept constant at all times and the complete combustion of the fuel can be maintained.

IPC: H04N5/92
Filed: 1994-08-18
Abstract: PURPOSE: To automatically adjust a frequency at the time of processing video signals by a digital system by performing a modulo arithmetic operation to standard low band carrier chrominance signals in response to a calculated line jitter amount and generating frequency-corrected new low band conversion carrier chrominance signals. CONSTITUTION: A horizontal synchronization conversion part 100 initializes the horizontal synchronization error Herror1 of a line immediately before to '0', separates digital horizontal synchronizing signals by system clocks from inputted horizontal synchronizing signals and counts clocks N. A calculation part 200 calculates a present line horizontal synchronization separation error Herror2 . The actual period of the horizontal synchronizing signals of a present line is calculated and the jitter amount ▵T1 of the present line is calculated. Then, a correction part 300 calculates a correction degree and then, the new low band conversion carrier chrominance signals New Fcu are generated.  A counter 400 substitutes the calculated horizontal synchronization separation error Herror2 of the present line to the horizontal synchronization error Herror1 of the line immediately before and repeats the same process to the next horizontal synchronization period after delaying one horizontal synchronization period 1H.

IPC: G06F1/12
Filed: 1988-08-03
Abstract: PURPOSE:To quickly obtain an output signal synchronizing with a clock pulse by using the D-FFs containing the master set terminal and the master reset terminals over two stages. CONSTITUTION:The asynchronous signals 11 are inputted to the input terminals D1 and D2 of the D-FF 1 and 2 containing the master set and reset terminals respectively. At the same time, the clock pulses 100 are inputted to the clock input terminals CP of the FF 1 and 2 respectively. The signal 11 is inputted to a master reset terminal MR1 of the FF 1 via a delay circuit 3. When the signal 11 changes to '1' from '0' before a period of set-up time, the terminal MR1 is negated before the rise of the pulse 100. Then the signal 11 is sampled and '1' is held by the FF 1 and 2 respectively. Thus the output 10 of the FF 1 and the output synchronizing signal 20 of the FF 2 are set at '1'. Then the signal 20 is set at '0' when the signal 11 is changed to '0' from '1'.
